" s," I! ii -legends Application filed March To all whom it may concern:

it known that l, licence llAYES; u cicizeu of the United States, residing at Glemvood Springs, in the county of bierlicl l, ,i'jlute oi Colorado, hove invented cermin new end useful improvements in Cushion lires; and l do hereby declare the lollovviiig to he s full clenr, exact descrip- L on of lhe invention, such as will enable others skilled in the art to which it s ope?- tnins to moire end use the same,

This invention relates to cushion tires and more particularly to that class in which a pier-alley oi splin s ere interposed between a rim and c creed member surrounding the rim uncl ih... tire embodied. in my invention involves a. number of novel features which will heroine 'tcr be fully explained.

One of the features of my invention resides in the met limit but u comparatively lhin rubber tread is provided and this so ield ii l e ed member of the tire that may :i'l u detached all my desired lime and i new tread substitute .l also connect. W the tread member, by means of lhe 'croed zolding device continuous lee-the! flaps which also secured to the rim of she lire t ere 3 preventing dual? or the like enlerl helnvecu the rim end the trend meniencl injuring the syringe or in other with their ziction' 1 else form the tire into semi-circular sections one end one section, including both the rim tread rncizihcrs lotted or recessed and for the recepiiou or one end of the other section which latter end is reduced for the purpose stared. ll to be understood however that by referring to the rim I do not mean to indicuie the rim oi the Wheel, which as a matter of feet is of usual ccnsicructim but 2:. rim-like section of she tire and l Will so designate this member of the tire ihroughout the specification and clniins.

In the accompanying drawings, Figure 1 is a side of a wheel employing a tire.

Patented New section, and, Fin. 7 is :1 View of one end of the other section.

Referring more specifically he the drowlugs the rim of the Wheel is indicated by the numeral 10 and the spokes by the numeral 11. The rim member of the tire is indicate-fl by the numeral 12 and is curved transversely to form a contour of the wheel rim l0 and the edges of the rim 12 are ext-ended 2, short distance above the edges of the Wheel 10 for u urpose to be hereinafter cleorl v stated. 'lhis rim 12 is preferably made oi: sheet metal and is bolted to the Wheel by means of bolts 13 as clearly shown in Fig. 3 of the drawings.

'lhe tread member of my tire comprises an annular body 14: which is substantially rectangular in cross section and is hollow as clearly shown in the transverse seciionc-l view of the drawings and this tread member is telescopically received in the rim hill; is normally held against movement entirely into the rim by means of helical springs 15 which are interposed belween the bottom of the rim and the under side oi the tread member and these springs are of such numher that they lie in close relation one to the other and they are secured to the :2 by means of U-bOl'lS 16 which ere engiigecl through the rims l2 and 1G and to the inner periphery of the tread member by means of suitable clips 17 which are formed intograil therewifih. It will be understood of course that the tendency of these springs normally force the tread member out from the rim at all times and at every point in she circumference of the tread member,

I have stated that the tread member is substantially rectangular in form but the edges of the member at its outer periphery are flanged as at 18 and the outer periphery is couvexcd transversely as at lfl'and formed integral with the edges of the flanges 18 and ill' equidistant points thereon are threaded. scucls 20 which are designed to be entered through openings 21 formed at corresponding intervals in eV band which has n !lnngc 23 mlnpled to fit snugly against the under side of the corresponding flange 18, the said bands being held secure upon "the flanges by means of nuls 24 which are engaged upon the threaded studs 20 and bear against the bonds. The body porlion of ouch band is curved in e greater are ihen the arc of curvature of the tread l?) and transverse hence is positioneci in spececi relation theire= Y to, the edge of the body portion of each hand being turneii siightiy inwardly toward the tread 1.9 as at 25 to firmly hold to the tread 1 a rubber strip 26 which is concave convexed i in cross section and preferably thicker at 1 its middle than at its edges. Ilow in order to prevent the entrance oi dust or other foreign matter between the rim 12 anti the tread member of the tiiG, I have provides leather flaps 27 which are secured at one of their edges one to each side or flange of the tread member by hevin their edges engaged between the flanges one the bends as clearly illustrator} iii the sectional view in drawings and at their other edges these riveted or otherwise secured to the rim 10,

In order that my .ey be readily psire plied to the Wheels now in use, the tire formed in a pair of semicircular sections one end of each isection being reduced to fit Within the opposite end of the other section in a. manner which will now he described,

@118 end of each of. the s ctiolos mentioned above or rather the ilm and. the tremi memhei" M is slotted as at 28 and respectively, the slot 28 being of the some configuration the cross section of the rim 12 who the slot 29 being suhstz'uitiolly rectangular. The other ends of the rim and tread members are reduced as indicated specti'vely by the numerals 30 and 31 UINi are eel-opted to he received in the slots 28'uud 29 respectively in the first mentioned ends of the other sections of the tire and the tread 19 is omitted throughout the rethiced ends of the section.

Formed in the sides of the reduced c216. portions of the rim are threaded openings into which are screwed bolts 32 W'iich project through slots 33 fOII'fiQd in the outer Wall of the slotted end portion of the rim and these looits ere provider with heads which when the tire sections have been iproperly bolted to the rim 0? the wheel and -rave hence heel their ends brought together, are tightene i.
